UFC middleweight Michael Kuiper (12-1) has had a second opponent fall to the wayside due to injury after replacement fighter Caio ‘Hellboy’ Magalhaes (5-1) was forced off the upcoming UFC on FX 7 card.

Stepping in will be Buddy Roberts (12-3) who coincidentally defeated Magalhaes in his Octagon debut last summer. Instead of squaring off at the FX event, the bout has been switched to the UFC on FOX 6 show.

News of the change was announced by UFC officials on Thursday afternoon.
